摘要
甲基丙烯酸甲酯 ( MMA)在无皂乳化剂条件下 ,加入少量的功能性单体 N,N一二甲基 ,N-丁基 ,N-甲基丙烯酰氧乙基溴化铵 ( DBMEA) ,合成了稳定的 P( MMA-DBMEA)共聚物乳液 .该共聚物乳胶粒呈现单分散分布。同时用 NMR研究了共聚物 ,并对 P( MMA-DBMEA)聚合物13 C进行了全归属。
Preparation of cationic copolymer latex of MMA with comonomer N, N-dimethyl, N-butyl, N-methacryloloxylethyl ammonium bromide (DBMEA) was carried out by soap-free emulsion polymerization. The 13 C NMR spectroscopy of P(MMA-DBMEA) polymes was studied by SW probe and CP/MAS probe. and 13C chemical shifts of the polymer were assigned.
